WATERPROOFING COMPOSITION.

No Drawing. Application filed June 28,

T 0 all whom it 'may concern:

Be it known that I, JOHN R. llYnR. a citizen of the UnitedStafesrosiding at Ilerkiiner, intlie county of l'lerkimerand State ofNew York, have invented certain new and useful ImprovementsCompositions, of which the following is a specification. Y

This invention relates to water-proofing fabrics and while havingespecial reference to paper is applicable to fabrics other than paperwith perhaps equal or greater benefits.

A further object of the invention is to provide a. water-proofing and afabric waterproofed thereby which is thoroughly pliable and whichpresents no fracture of the Waterproofing resulting from the bending ofthe fabric thus water-proofed.

A further object of the invention is to provide means whereby paraflineand rosin,both well known water-proofing materials, may be applied to afabric to provide a successful and satisfactory water-proofing andwaterproofed fabric.

.A' further object of the invention is to mix with paraffine and, rosinat a temperature suflicient to maintain liquidity Epsom salts whichproduces ebullition and thereby enables the fabric immersed therein tobecome coated and partially impregnated with the material which isotherwise too heavy for manipulation.

It is probable that the ingredients above referred tdmay be employed inproportions varying within certain ranges, but I have found that amixture of 43% parafiine, 55%

' of rosin, and 2% of Epsom salts, by weight,

produces an ideal compound for the purpose and that when maintained inliquid COIldl? tion by heat and paper,'or other fabric, immersedtherein, provides an ideal waterproofing and an ideal water-proofedfabric.

In the actual carrying out'ofthe process the material 'is maintained inliquid cond'ition by heat in any convement vat'or recep- 1 Specificationof Letters Patent.

manner the superfluous material is removed.

- What I claim is: 4

, 1. A water-proofing composition comprising paraiiine, rosin and Epsomsa'lts.

2. water-proofingcoating composition comprising paraflme, rosin andEpsom salts comminglcd and maintained in liquid c0ndition by heat.

3. A water-proofing composition comprising approximately 43% ofparafline, of rosin and 2% of Epsom salts, by wei ht.

4. A water-proofed fabric comprising a sheet of material having adheringto its exterior a composition of parafline. rosin and Epsom salts.

5. A water-proofed fabric having adhering to its exterior andimpregnating its interstices a composition of paraffine, rosin and Epsomsalts;

6. A water-proofed fabric comprising a sheet of material having adheringtoits exterior a composition of approximately 43% parafline, rosin and2% Epsom salts.

7. A water-proofed fabric comprising a sheet of material having itsinterstices filled with a composition of .parafline, rosin and Epsomsalts.

81A water-proofing material comprising a wax, a gum and a salt ofmagnesia.

9. A water-proofing composition comprising a mineral wax, a resinousmaterial and a salt of magnesia.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
